CARRIAGE ron FLYING 'macnmns.

Application filed April 2, 1928. Serial 110. 828,412.

To all whom it may concern:

Be it known that I, CLAUmUs DORNIER, a citizen of Germany, residing'at Friedrichshafen-on-the-Bodensee, Germany, have invented certain new and useful Improvements in Carriages for Flying Machines, of which the following is a specification.

My invention relates to flying machines and more particularly to the landing gear of large or giant-flying machines. It is an object of my invention to improve the strength of such landing gear and the stability of the machine during starting and landing.

The landing gear of flying machines as hitherto constructed comprises a plurality of parallel wheels designed to uniformly .and in common support the machine. Landing gear of this kind, besides possessing a consider; able weight, is liable to be damaged under the action of the bending stresses arising during the landing of themachine. On uneven ground the machine further has a tendency to reverse when starting, according as the wheels on one side run on a higher or lower level than'those on the other side, which are under the same| load.

It is an object of my invention to obviate that drawback. I attain this end by means of a landing gear having a comparatively large starting wheel anranged directly below the hull or body in the plane of symmetry of the hull and is apt to carry substantially alone the entire weight of the machine. As the arrangement may easily be so devised that the starting wheel lies at least approximately below the mass centre of the entire machine and at a short distance therefrom it may at the same time form as body and which is practically integral.

ported in the side walls of the casin Rigid outriggers e extending on either si e of the casing d and wheel c have fixed to their ends small wheels or runners f, -which mainly serve as stabilizing members in case that the machine, while starting or landing, should be inclined to one side, and areresiliently connected with the outriggers. Preferably these auxiliary wheels or runners are arranged to touch the ground before the su porting wheel ccomes in contact therewi I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur' to a skilled in the art.

I claim:

1.-Flyin machine comprising in combination, a nil, a main bearing plane sub stantial] flush with. the u per surface of said h a; wheel mount fbrmin art of and extending downwards from t e portion of said hull, a wheel a p orted in said wheelinount in the. longitudinal axis of said hull and a stump wing or auxiliary bearin said w eel mount.

2. Flying machine comprisi in combination, a hu a main bearing p ane substantially flush with the upper surface of said hull, a wheel mount forming art of and extending downwards from the ottom ortion of said hull, a wheel supported. in sai wheel mount in the longitudinal axis of said, hull, a stump or auxiliary bearing plane extending on either side of said wheel mount and supporting means at the outer end of each stump ottom plane extending on either side of 3.. Flying machine comprising in conibination, a hu11','a main bearing plane substantially flush with the upper surface f said 5 tendingdo'wnwirds fromthe ott'om' oitioh of said hull, 5 Wheel Supported in sai wheel mount inthe longitndineiaxis of said hull,

a stump wing or aux'iliar bearing plane extending on either side 0 said wheel moum and'resiliently mounted runners at the outer 10 end of each stum win .V I 'l In testimony w ered? I aflix my signature.
